The async settings gate added in f0d96f8e called
shouldStartDaemon() inside Promise.resolve(...).then(...) with no
catch. If loadDesktopSettings() rejects (corrupted JSON, FS error),
the daemon never starts, no error renders on the splash, and the
retry button repeats the same silent path.
Add a recordError method to DaemonStartService and an onGateError
callback to startDaemonIfGateAllows / startHostRuntimeBootstrap.
_layout.tsx wires it through so a gate rejection populates
lastError, the splash shows the failure, and retry has signal.
HostRuntime self-boots via boot() and emits state through existing
subscribeAll plumbing. DaemonStartService runs in parallel: on success
it upserts the connection, which HostRuntime's syncHosts already wires
into a controller; on failure it emits an error.
The bootstrap no longer awaits daemon-start before letting saved-host
controllers connect. index.tsx resolves the redirect from
useEarliestOnlineHostServerId + useDaemonStartLastError subscriptions,
not from a procedural promise. The splash error is derived state:
splashError = !anyOnlineHostServerId ? daemonStartError : null. Retry
calls only DaemonStartService.start().
Deletes initializeHostRuntime, setupDesktopManagedConnection,
addConnectionFromListenAndWaitForOnline, bootstrapDesktop on the store,
waitForAnyConnectionOnline (now unused in production), and the
phase enum. Net -623 lines.
